Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an integrated skid-mounted device for the adsorption and recovery of heavy metal wastewater. Background Technology

[0002] Heavy metal wastewater refers to wastewater containing heavy metals (such as mercury, cadmium, lead, chromium, nickel, copper, zinc, arsenic, etc.) discharged during industrial production processes in mining, metallurgy, machinery manufacturing, chemical, electronics, and instrumentation industries. These heavy metal ions are toxic and hazardous, and therefore pose a great threat to the environment and human health.

[0003] Treatment of heavy metal wastewater mainly includes physical treatment, chemical treatment, and biological treatment. Physical treatment removes heavy metal ions through methods such as filtration, centrifugation, and adsorption. For example, Chinese patent CN210764829U discloses an industrial wastewater treatment device with a heavy metal adsorption and recovery mechanism. It has magnetic components installed at the bottom of the filter tank, which magnetically magnetizes the movable cover on the inner wall of the filter tank, thereby adsorbing heavy metals from the wastewater for subsequent recovery. This method can meet certain usage requirements.

[0004] However, the magnetic components in the aforementioned patent are poorly arranged, located only at the bottom of the filter box. When the wastewater flows, the magnetic adsorption cannot completely remove the heavy metals, resulting in poor overall adsorption performance.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide an integrated skid-mounted device for the adsorption and recovery of heavy metal wastewater.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0031] like Figures 1 to 7 As shown, an integrated skid-mounted device for heavy metal wastewater adsorption and recovery according to one embodiment of this utility model includes a base 1, a treatment tank 2, a liquid injection mechanism 3, a release mechanism 4, and a collection tank 5. The treatment tank 2 is mounted on the base 1. A conical partition plate 201 is provided inside the treatment tank 2, forming a sedimentation chamber and a liquid outlet chamber between the conical partition plate 201 and the inner wall of the treatment tank 2. An inlet pipe 202 and an outlet pipe 203 are installed on the treatment tank 2. The inlet pipe 202 communicates with the sedimentation chamber, and the outlet pipe 203 communicates with the liquid outlet chamber. A flow mechanism is installed on the conical partition plate 201. The liquid injection mechanism 3 is mounted on the base 1 and located on one side of the treatment tank 2. The release mechanism 4 is mounted on the treatment tank 2 and cooperates with the liquid injection mechanism 3 to precipitate heavy metals in the wastewater. The collection tank 5 is mounted on the base 1 and located on one side of the treatment tank 2. A collection pipe 501 connects the collection tank 5 to the treatment tank 2.

[0032] When treating heavy metal wastewater, the flow mechanism is closed, and the wastewater is transported to the sedimentation chamber through the inlet pipe 202. Then, the injection mechanism 3 delivers a capturing agent into the sedimentation chamber through the release mechanism 4, which precipitates the heavy metals in the wastewater. The precipitated heavy metals fall onto the conical partition plate 201. When it is necessary to discharge the liquid in the sedimentation chamber, the flow mechanism is first opened, and the liquid in the sedimentation chamber enters the outlet chamber through the flow mechanism, and then is discharged from the treatment tank 2 through the outlet pipe 203 for further treatment. When the liquid in the sedimentation chamber is completely discharged, the release mechanism 4 scrapes the heavy metal ions on the conical partition plate 201 into the collection tank 5 for subsequent recovery of the heavy metals in the collection tank 5.

[0033] like Figures 1 to 7 As shown, the flow mechanism includes a filter screen 2011, a liquid collection hood 2012, and a flow pipe 2013. The filter screen 2011 is located on the inclined surface of the conical partition plate 201, the liquid collection hood 2012 is located on the lower side of the conical partition plate 201 and covers the filter screen 2011, and the flow pipe 2013 is connected to the liquid collection hood 2012. When it is necessary to discharge the liquid in the sedimentation chamber, the liquid passes through the filter screen 2011, making it difficult for the precipitated heavy metal particles to be discharged, and the liquid enters the outlet chamber through the liquid collection hood 2012 and the flow pipe 2013.

[0034] Preferably, the liquid collection hood 2012 is installed on the lower side of the conical partition plate 201 by screws, and a first control valve is installed on the flow pipe 2013 to control the opening and closing of the flow pipe 2013.

[0035] The treatment tank 2 is equipped with a first observation plate and an inspection door on its outer wall. The first observation plate allows observation of the wastewater volume in the sedimentation chamber and the sedimentation of heavy metal particles on the conical partition plate 201. The inspection door facilitates the inspection and maintenance of the conical partition plate 201.

[0036] like Figures 1 to 7 As shown, the injection mechanism 3 includes a storage tank 301, a heavy metal ion scavenging agent 302, and a submersible pump 303, with the submersible pump 303 housed within the heavy metal ion scavenging agent 302. The storage tank 301 stores the heavy metal ion scavenging agent 302 and the submersible pump 303. The heavy metal ion scavenging agent 302 can chemically react with various heavy metal ions in wastewater, rapidly generating an insoluble, low-water-content, easily filtered flocculent precipitate. Combined with the function of the filter screen 2011, this achieves the purpose of removing heavy metal ions from the wastewater. The submersible pump 303 is used to extract and transport the heavy metal ion scavenging agent 302.

[0037] Preferably, the submersible pump 303 has a power of 0.75kW-3kW and a flow rate of 5-30m³ / h. 3 / h, head: 10-50m.

[0038] The submersible pump 303 is connected to an infusion tube 304. The heavy metal ion scavenging agent 302 extracted by the submersible pump 303 is delivered through the infusion tube 304.

[0039] In addition, the outer wall of the storage tank 301 is equipped with a second observation plate and a replenishment pipe. The capacity of the heavy metal ion capture agent 302 can be observed through the second observation plate so that it can be replenished in a timely manner through the replenishment pipe.

[0040] like Figures 1 to 7As shown, the release mechanism 4 includes a motor 401, a rotating shaft 402, a hollow sleeve 403, and a pair of hollow tubes 404. The motor 401 is mounted outside the treatment tank 2. The rotating shaft 402 is connected to the output end of the motor 401 and rotatably connected to the conical partition plate 201. The hollow sleeve 403 is mounted on the side wall of the rotating shaft 402 located outside the treatment tank 2, and the rotating shaft 402 is rotatably connected to the hollow sleeve 403. A pair of hollow tubes 404 are offsetly connected to the side wall of the rotating shaft 402 and are disposed within the sedimentation chamber. When the motor 401 is running, the motor 401 can rotate the rotating shaft 402, which in turn drives the pair of hollow tubes 404 to rotate. The hollow sleeve 403 is used to temporarily store the heavy metal ion scavenging agent 302 so that the heavy metal ion scavenging agent 302 can be transported to the sedimentation chamber.

[0041] The hollow sleeve 403 is fixedly connected to the top wall of the treatment tank 2, and a sealed bearing is connected between the hollow sleeve 403 and the rotating shaft 402. The hollow sleeve 403 is also connected to the infusion pipe 304. When the rotating shaft 402 rotates, the hollow sleeve 403 does not rotate with it. The sealed bearing design prevents the heavy metal ion capture agent 302 from leaking easily.

[0042] In addition, the rotating shaft 402 is provided with a flow cavity 405 and multiple through holes 406. The flow cavity 405 is connected to the interior of the hollow sleeve 403 through the through holes 406, and the hollow tube 404 is connected to the flow cavity 405. The heavy metal ion capturing agent 302 in the hollow sleeve 403 enters the flow cavity 405 through the through holes 406 and can be transported in the flow cavity 405, and finally enters the hollow tube 404.

[0043] Specifically, the hollow tube 404 is provided with multiple evenly distributed liquid outlet holes 407, which are vertically downward. The heavy metal ion scavenging agent 302 inside the hollow tube 404 can enter the sedimentation chamber through the multiple liquid outlet holes 407. With the rotation of the hollow tube 404, the heavy metal ion scavenging agent 302 can be evenly sprayed into the sedimentation chamber to ensure the precipitation effect of the heavy metal ion scavenging agent 302 and heavy metals in the wastewater.

[0044] In addition, a scraper 408 is fixedly connected to the side wall of the rotating shaft 402, and a rubber plate 409 is installed on the scraper 408. The rubber plate 409 corresponds to the inclined surface of the conical partition plate 201. Since the scraper 408 is fixedly connected to the side wall of the rotating shaft 402, when the rotating shaft 402 rotates, the scraper 408 and the rubber plate 409 can rotate synchronously. The rotating rubber plate 409 can discharge heavy metal particles on the conical partition plate 201, so that the heavy metal particles can be transported into the collection box 5 for subsequent recycling of heavy metals.

[0045] like Figures 1 to 7As shown, the side wall of the treatment tank 2 is provided with a discharge port 204, which is located on the upper side of the conical partition plate 201. One end of the collection pipe 501 is located inside the discharge port 204. When the scraper 408 and the rubber plate 409 rotate, the rubber plate 409 can scrape the heavy metal particles on the conical partition plate 201 into the discharge port 204. The heavy metal particles in the discharge port 204 enter the collection box 5 through the collection pipe 501 for temporary storage.

[0046] A second control valve is installed on the collection pipe 501 to control the opening and closing of the collection pipe 501. That is, the second control valve is in the closed state when wastewater is settling. When it is necessary to discharge heavy metal particles, the second control valve is in the open state.

[0047] In addition, a control box is installed on the outer wall of the treatment tank 2. The first control valve, the motor 401, and the second control valve are electrically connected to the control box for easy operation.

[0048] Specifically, the collection box 5 is equipped with a dividing screen, which can separate heavy metal particles from the liquid.

[0049] In addition, the outer wall of the collection box 5 is equipped with a discharge door and a sewage discharge pipe. Heavy metal particles in the collection box 5 can be removed through the discharge door, and sewage can be discharged through the sewage discharge pipe.

[0050] In summary, this application integrates the treatment tank 2, injection mechanism 3, release mechanism 4, and collection box 5 into a single skid-mounted unit on the base 1 for convenient operation. Through the coordinated operation of the conical partition plate 201, the flow mechanism, the heavy metal ion scavenging agent 302, the infusion pipe 304, the hollow sleeve 403, the flow chamber 405, and the hollow pipe 404, the heavy metal ion scavenging agent 302 in the storage tank 301 can be transported to the sedimentation chamber, thereby precipitating heavy metals in the wastewater for recycling. By rotary spraying the heavy metal ion scavenging agent 302, the contact effect between the heavy metal ion scavenging agent 302 and the heavy metals in the wastewater is improved, thus enhancing the precipitation effect and preventing heavy metals from being discharged with the liquid. Through the coordinated operation of the motor 401, the rotating shaft 402, the scraper 408, the rubber plate 409, the collection pipe 501, and the collection box 5, the precipitated heavy metals can be collected for recycling.

[0051] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure.
